SKF NK 9/12 TN Series Roller Bearing, 9mm Inside Diameter, 16mm Outside Diameter - NK 9/12 TN

This roller bearing is a needle-type component designed to support radial loads in Compact mechanical assemblies. It operates in applications requiring a cylindrical bore Interface and an open-end configuration, delivering consistent rolling motion where space is restricted and high rotational speeds are needed.

Features and Benefits:

• Non-metallic cage reduces friction for smoother operation
• Steel rollers provide high contact strength for load endurance
• Flanged race ensures secure axial location during service
• Single-row layout minimises assembly thickness for Compact builds
• High limiting speed of 34,000 rpm supports Rapid rotational systems
• Dynamic capacity of 4.4 kN enhances performance under continuous motion

Applications

• Suitable for actuator shafts in automated systems
• Ideal for precision motors in electronics manufacturing
• Used with rotary encoders in control equipment
• Can be used for gearbox idler shafts in electrical drives
• Used for guide rollers in pick-and-place machinery

What is the bearing’s static behaviour under standstill loads?

The bearing provides a static load capacity of 5.2 kN, allowing it to sustain stationary radial loads without permanent deformation.

How does the open-end design affect maintenance access?

The open configuration permits direct inspection of the rolling elements and facilitates relubrication or replacement without disassembling surrounding housings.

Which component contact surfaces are specified for compatibility?

The inner Interface is cylindrical and requires a 9mm bore mating journal, while the outer support conforms to a 16mm external seating diameter.

What construction materials influence its thermal and wear properties?

The rollers and races are formed from bearing-grade steel, combined with a non-metallic cage to balance wear resistance and low-friction operation.
